Bug 311790

Application: kate (3.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Linux Mint 13 Maya

-- Information about the crash:
Linux Mint 13 Maya running on a MacBook Pro. Uptime 5 days, 19 hours and 38 minutes (for what it's worth).

In general, I was switching back and forth among a number of applications to gather information I was entering into a file being edited with Kate (GREAT application!). The crash occurred while typing. I wasn't looking at the screen as I was typing (I was reading some hand-written notes I was entering).

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
